DSMlink, first startup.

[XiKeiyaZI]

Ah, well.. considering that I'm taking this seriously and attempting to read/research/get input, I can't really evaluate the humor in that one. However, of course a problem exists : I'm a Link-Noob. Thanks for pointing out the obvious. Now, offer some decent advice as to why my 02 keeps dropping at random until I kill the engine and restart it 1-2 times.

 

[LandoAWD]

I've had Link for 2 years, and I'm still a noob.

 

[SpawnedX]

Bro, you are asking for me to make assumptions on something I am not familiar with. I runmy wideband from my DP and have my stock narrowband in the O2 housing. I don't have the problem or any idea about that setup. To me it doesn't sound like the best option, but tuning isn't my thing, DynoTech will be tuning my car.

 

[LiquidX]

You'll need to post a new log for use to see what the problem is Keiya. We'll get you all situated and running well.

 

[XiKeiyaZI]

I'll get a good cruise long this afternoon from my driveway on first start and more. Any recomendations on total drive-time/length?

 

[LiquidX]

Get an idle log on there as well with it at operating temperature.

 

[snowborder714]

Cruise logs really don't need to be long. It's just for a basic fuel trim check. An idle log will be a bit more helpful.

 

[XiKeiyaZI]

Ah, okay. I'll go start it and get a log off it from a start for about a minute then.

 

[XiKeiyaZI]

Here's an Idle Log with a bit of revving here and there, smooth for the most part.

 

[LiquidX]

First, click on the check box for "simulate idle switch". Yours doesn't appear to be working from the TPS.

You want to adjust your TPS to 0.64 when off throttle so you'll want to unbolt it and slowly rotate it until it reads 0.64v.

Log ICSPosition as you have your target idle set to 1000 and you are idling at 750. So you may have your BISS adjusted wrong and the ICS has no adjustment left. So log that and you want it around 40 by slowly adjust the BISS and letting the ICS reposition itself.

Proper temperature you want when doing a fully warm log is at least 180* BTW.

Put a name for the wideband and select it under "captured values" i.e. hit F10 so you can log it.

You have a code for a knock sensor malfunction. Have you checked to make sure it's not leaking goo and it's plugged in?

So get those fixed and then post up a new log so we can assess your fuel trims.

Yes Captain my Captain. You could hop on Aim as well if you want. I'll be heading out with the laptop, of course.

 

[LiquidX]

I'll see what I can do, I'm heading to bed in a little bit as I actually have to wake up for work tomorrow for once.

 

[snowborder714]

.63v, not .64v

 

[XiKeiyaZI]

o.- Yeah yeah, I did it by hand and apparently tapped it when tightening it. Leave me alone.

New log tonight. Scott helped me get a LOT of things in line. It's running much smoother, no 02 issues, and drives quite a bit better. I also found out that my knock sensor was a bit loose which was likely contributing to the Knock.

 

[LiquidX]

Hmm I could have sworn I read 0.64. Well it's only .01v difference . You're welcome Kei. Just get that new log up for us to see.

 

[XiKeiyaZI]

New Idle Log.

I want to go ahead and press on that my 02 KEEPS dropping off. I normally have to kill/start the engine 2-3 times before it finally picks up, starts switching, and continues to function properly. Any ideas as to what this might mean? After Scott helped me adjust my idle the other night, it worked fine for a day or two, but now it's back to doing the same thing.

 

[LiquidX]

In the log your o2 is working fine.

 

[XiKeiyaZI]

Yeah, but I can promise you that if I shift to Reverse to back out of my driveway it will stop functioning properly. I could get a log of that happening.

So how does the log look thus far?

 

[LiquidX]

Please post the log then if you would so we can see what it's doing.

So far the log looks alright. Still needs some tweaking as your CombinedFT is averaging -2% and I know you can get that closer to 0% more consistently especially seeing the -4% on there.

AirflowPerRev needs bumped up as you are dropping down to 0.22 gm/rev. Make sure to capture the value for the radiator fan. When that is on, your AirflowPerRev will alter due to the fan blowing air around. You want to tune when the fan is not running.

You can also clear your knock sensor CEL code on the DTC tab.

 

[XiKeiyaZI]

Some more tweaking with the Deadtime and Global then?

 

[XiKeiyaZI]

Should hop on AIM later if you can.

 

[XiKeiyaZI]

New Logs showing the 02 dropping off. The second log, I had to kill and start the engine a few times before it started switching again.

 

[DSMReviver]

I have my link for 2 and 1/2 years now and what you all just said is going through my ears. . WTF

Then again, my cars is been in the shop most of the time with polk performance. With Dave working his magics on link, im glad i don't have to do anything.

 

[XiKeiyaZI]

Fresh Idle log. Starting to look better, no?

I'm so ready to get into more. ;P

 

[LiquidX]

That idle looks great

Only 2 things pop out at me. Your ICS is at 50 and your TPSvolt is at 0.59v. Try dropping your target idle to 900 and see how everything is sitting.
